Great read, thanks. This is a very interesting subject to me. A couple of years ago I read a theory about alien life that was a bit different from this:
Given the age of our universe, sun, earth and humans:
Universe 14 000 million
Sun 4 600 million
Earth 4 550 million
Earth Life 3 500 million
Humans .2 million (200,000 years)
The probability of some alien life being within say, a range of [-.5 mllion, .5 million] of the life on earth is VERY slim. It is most likely that life out there is either in very early stages (protezoric) or that it is way farther than our current form (how will humanity look like in say, another 500,000 years?, assuming it continues to exist and evolve)
